Unfair treatment by ABSA Vehicle Finance

As a long standing customer of over 20 years with ABSA, (with a credit score of over 650), I app**** for vehicle finance with ABSA. The bank, through Thandeka Ngxangane, requested for clarity about additional income which I duly provided albeit she was a bit cold and harsh and appeared to have made a decision to reject it prematurely without evidence. I was suprised that after all that clarity and requested documents explaining additional income, she rejected the documents with no explanation. Strangely, one of the document was accepted some years ago when i app**** for finance. My sense is that the bank does not understand my income model against the "Know Your Customer" principle and further I sense I was not treated fairly probably due to the frosty exchange with Thandeka Ngxangane. The local ABSA branch were also suprised with her feedback with no explanation. I am shopping for a new bank which will attempt to Know me as a valued customer and treat me fairly and will move my bond/vehicle finance and personal cheque accounts to them.
